Reporting from Trafalgar Square

About a 15-minute walk away from Covent Garden is Trafalgar Square, where a London Air Ambulance landed earlier. Musician Andrea Borin was busking here at the time.

He says it’s “not the first time” he’s seen a helicopter land in the square during an emergency.

Andrea, 26, has been playing here for about five years, and says he and other buskers “stopped” what they were doing when the helicopter arrived “out of respect”.

He says he saw paramedics leave the helicopter and dash off down the road.

The helicopter landed for about an hour before leaving, he adds.

A woman has been arrested after four people were stabbed in central London.

Here's a look at what we know - and don't - about the incident.

What we know

• Police were called to reports of a stabbing in London's Covent Garden at about 12:30 BST on Wednesday
• Four men, aged 34, 39, 42, and 52, were taken to hospital for treatment, two have since been discharged
• A 47-year-old woman has been arrested on suspicion of possession of an offensive weapon and assault and remains in police custody, the Met says
• The Metropolitan Police says it believes the incident be "isolated and mental-health related"

What we don't know

• We've had no official details from the police about what kind of weapon was used in the incident
• We don't yet know the full condition of the two patients that remain in hospital, other than that their injuries are not believed to be "life-changing"

There has been a heavy police presence in Covent Garden throughout the afternoon.

Officers have been stationed around the area, which is one of the busiest areas in central London. New photos taken at the scene show that police are carrying out an investigation behind a cordon.

This is an area with quite a few businesses, including pubs, restaurants and theatres.

Some of those who I’ve spoken to say they arrived for their work shift after police made an arrest, but could see the chaos around the police cordons.

One member of the public, who asked not to be named, says he was inside the Shaftesbury Theatre when the incident occurred.

He says he came outside and saw blocked roads, multiple police cars and ambulances - a scene unusual for the area, he adds.

Covent Garden is a busy and touristy area in the heart of central London.

Just minutes away from the British Museum, the area is known for its shops and restaurants.

The area is in the city's West End and home to several theatres. Head south from Endell Street - where the stabbing took place - and you will hit the River Thames.

Also nearby is Trafalgar Square, popular with tourists, where a London Air Ambulance landed earlier to help treat the stabbing victims.

Two of the victims involved in today's incident have injuries that are not believed to be life-threatening or life-changing, the Metropolitan Police has said.

The other two victims have been discharged from hospital, a statement from the police force adds.

"Four men – aged 34, 39, 42, and 52 - were found with stab wounds and assessed at the scene by paramedics," it reads.

"They were taken to hospital where two remain with injuries that are not believed to be life-threatening or life changing. The other two victims have since been discharged."

The Metropolitan Police believes the incident is isolated and "mental-health related" according to Chief Superintendent Jason Stewart.

In a statement on X, he says: "Officers responded within minutes of this incident after receiving a number of reports.

"While still at an early stage of the investigation, we would like to reassure the community that we currently believe this to be an isolated, mental-health related incident.

"A visible police presence will remain in the area while evidence is gathered at the scene and we thank the public for their understanding."

Tim Keates, a painter working on a salon, says he has been in the area since 11:30.

He tells me he didn’t realise something had happened until police cordoned off the intersection.

Keates, 61, says he saw a number of police and dozens of paramedics, but not the incident itself.

Members of the public would approach the cordon down the road and then turn back and walk past him.

He has been working in the area since the start of the week and says it is “busier” in the streets today than on previous days.

Lottie Johnson and Ben Ormonde are visiting the capital for the day.

They were sitting on a bench at about 12:30, when they saw police cars, incident response vehicles and paramedics arrive on the corner of High Holborn and Endell Street.

“There were so many emergency services arriving” they said.

“We could see a man being assessed by ambulance crews - he was walking and didn’t outwardly appear injured, we couldn’t see blood, but he was put inside the ambulance”.

I’ve just spoken to Angel Daden.

She was in a spin class at Oasis Sports Centre when someone came in and told her “people are being stabbed outside”.

Angel, 55, says she came outside for “a quick look” and saw a bandaged person heading into an ambulance.

But she didn’t see who was carrying out the attack.

Angel tells me she hasn’t experienced something like this in the 18 years she’s lived in the area.

In the past few minutes, police have removed their cordon and reopened the area to traffic and pedestrians.

Much of the police activity has been focused on a building on the corner of High Holborn and Endell Street which belongs to the homeless charity, St Mungo’s.

A police cordon near the scene has been removed and people are now able to walk through as normal.

Officers are telling members of the public that things are under control.

The sound of a helicopter overhead remains.

Earlier today, an air ambulance could be seen taking off from Trafalgar Square, with a large crowd gathered in the tourist hot spot.

The air ambulance departed with no patients on board - they were ultimately transported to hospital by road.

There is a large police presence in Covent Garden after four men were taken to hospital with stab wounds.
